The J.L. Mott Ironworks poured veneer over the inside of cast iron little clawfoot baths in 1873, making a smoother, glass type finish. This bath type turned into the standard in the US until the inherent fiberglass adaptation tubs had its spot in the 1930’s.
The Kohler Company added legs to their cast iron and steel horse trough/hoard scalder in 1883, bringing about their first delivered bath. The clawfoot graced the legs and pushed the organization into a powerhouse starting there on.
